UNITED; STATES PATENT THOMAS H. HATHAWAY, OF NEW BEDFORD, MASSACHUSETTS.

MUSIC-LEAF TURNER.

SPECIFICATION forming part of Letters Patent No. 321,599, dated July 7, 1885.

Application filed August 14, 1884. (No model.)

To all whom it may concern:

Be it known that I, THOMAS H. HA'IHA- WAY, of New Bedford, in the county of Bristol and State of Massachusetts, have invented a new and Improved MusicLeaf Turner, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved music-leaf turner of simple construction which operates rapidly and never fails.

The invention consists in the construction and arrangement of parts, as will be hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a perspective view of my i1nproved music-leaf turner. Fig. 2 is a crosssectional view of the same.

The music-rack A, having the usual bottom ledge, B, is supported by a standard, 0, having a suitable base.

On the center of the rack A a shaft, D, is journaled, which extends from top to bottom and projects beyond the ledge, 011 which projecting end a bevel-pinion, E, is rigidly mounted and engages with a bevel cog-wheel, F, on a shaft, G, held a short distance from and parallel with the ledge B. A rod, H, held on an eccentric or crank pin, F, of the wheel F, extends down to and is connected with a foot-lever, J, pressed upward by a spring, K.

On the shaft D a rectangular wire frame, L, is held to turn with the shaft, and on the top and bottom pieces of the said frame sliding sleeves M are held, which can be locked in place by screws N. The said sleeves M are connected by a wire, 0, on which two or more small magnets, P, are held. The wire 0 can be adjusted a greater or less distance from the swinging end of the frame by means of the devices shown, or by any other suitable devices. On the left-hand side of the rack two projecting pins, R, or like projections are held in such positions that the frame L must strike against them when itswings on 50 the left-hand-side of the rack. Iron or steel springclips S or other metal clips are snapped on the swinging edges of the levers T, or are fastened. in any other suitable manner, so that the metal shows on the upper side.

The operation is as follows: To turn a leaf, the operator depresses the foot-lever J, whereby the frame L is swung from the right to left hand side ofthe rack or desk. The metal clips S on the uppermost leaves are held to magnets, and the said uppermost leaf is thus carried or swung over upon the left-hand side of the rack with the frame L. The frame L strikes the projections R, and the leaf is knocked off by the sudden jar or shock, and drops upon the left-hand side of the rack. The foot-lever J, is released and forced upward by the spring K, and thereby swings back the frame L upon the right-hand side of the rack. The clips S of 70 the top leaf again catch on the magnets, and

so on.

With slight modifications, the above-described device can be applied on pianos, organs, 850.

It is evident that the magnets may be secured on the leaves and metal pieces on the wire O; but I prefer the arrangement shown.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a music-rack, of a wire parallel with the swinging axis and adjustable a greater or less distance from the same, and of magnets held on the said vwire, substantially as herein shown and described.

2. The combination, with the rack A, of the swinging frame L, the sliding pieces M on the top and bottom piece, the wire O, con- 0 necting the top and bottom piece, the screws N, and the magnets l? on the wire O, substantially as herein shown and described.-

3. The combination, with a music-rack, of a swinging frame carrying magnets, and of stops on the left-hand side of the rack, substantially as herein shown and described.

4. The combination, with the rack A, of the swinging frame L, having a wire parallel with the swinging edge, which wire is adjustable in relation to the swinging edge,and earlever J, and the spring K, substantially as ries leaf-engaging devices, substantially as herein shown and described.

herein shown and described.

5. The combination, with the rack A, of THOMAS HATHAWAY' 5 the shaft D, the frame L on the same, the WVitnesses:

bevel-pinion E on the lower end of the shaft, OSCAR I GUNZ, the bevel cog-wheel F, the rod H, the foot 0. SEDGWIOK.
